Ken, one reason the Ultra Stick appears "beyond repair" is that it is all lite ply. It's light and fairly strong when they put it together, but, when it breaks there's not much left. I know one or two who would have repaired it. Everyone else I fly with would have stripped and tossed the airframe.

Since you want to build the next one, here are a couple of suggestions:
Great Planes PT-40 or 60. The GP trainer kits have a mostly balsa fuselage where many other brands use lite ply. If/When the balsa planes crash, the pieces are usually bigger than if they were lite ply. In my mind the 60 size would be a better match for your Saito .82
Sig Astro Hog. This is an old style, all balsa, "builders kit" that will really challenge you but it is a great flying model that you should be able to fly with no problems. Mine (in my avatar) had a .70 four stroke and it flew very well. My brother currently has one with a .91 four stroke that he thinks is better. Your .82 would work great on it.
